摘　　要：针对导弹水下发射呈现出干扰量大、干扰因素随机性大,弹道参数变化急剧等特点,为研究水下发射环境对导弹出水运动的影响,基于埃克曼无限深海漂流理论和二阶Stokes波理论,采用流体体积法(VOF),建立了风海流模型和五级海况下二维、三维数值波浪模型,并通过动网格技术,实现了海流、波浪及导弹运动的耦合计算。结果表明,导弹在出水过程中力学环境会发生很大的改变,运动姿态变化较大,该综合仿真系统在一定程度上解决了导弹水下发射的非线性非定常问题。When a cruise missile is launched underwater,the interfering factors are great and random,and the parameters of the ballistic trajectory change so much. To study the effect of underwater environment of missile＇s process out of water,using volume of fluid method（ VOF）,wind current model and the 2D and 3D numerical wave model of five sea condition are established based on the theory of infinite deep Ekman drift and the second order Stokes wave theory. Through the dynamic mesh technique,the coupling calculation of wave,current and missile motion is achieved. The results shows that a missile＇s mechanics environment and attitude would have a very big change during the process out of water. It can solve the problem of the nonlinear unsteady problem of a missile launched underwater to some extent.
